Keep a flowering primrose close to its nursery root-ball size, moving only about 1 inch wider when repotting is necessary. The flower display spreads beyond the small fibrous roots and should not determine diameter.

Choose a modest draining pot about 1 inch wider than the root ball. Thyme forms a low woody mound, but its outward stem spread should not be mistaken for a need for a broad reservoir of damp soil.

Use a four-inch pot for one young plant, then size up as roots fill the container. Crowded supermarket clumps should be divided; a large group in one small root ball competes for light, water, and airflow.

Choose a draining pot about 1–2 inches wider than the woody root ball. Rosemary needs room for roots but suffers in a large volume of slow-drying mix; strong light and airflow matter more than generous diameter.

Use a small pot only about 1 inch wider than the root ball. Emerald Ripple Peperomia has a compact root system and stores some water in its fleshy leaves, so oversized containers stay wet too long.

Choose a pot about 1 inch wider than the measured root mass. This plant spreads by short underground rhizomes, so a modest width increase is more useful than a deep reservoir of unused, wet mix.
